Milwaukee SDS Max 4CT MX4™ 9/16″ X 8″ X 13″

MAXIMIZING UPTIME IN REINFORCED CONCRETE

When you’re drilling deep into reinforced concrete, the transition from aggregate to rebar is where most bits fail. The Milwaukee MX4™ 4-Cutter SDS Max bit is engineered to handle that impact without the catastrophic lock-up that snaps lesser accessories. By utilizing a solid head carbide and integrated rebar guards, this bit maintains its structural integrity under the high-load cycles of an SDS Max rotary hammer. The sharp centering tip ensures your anchor placement is precise, while the optimized flute geometry clears dust efficiently—reducing friction-induced heat and extending the runtime of your high-output batteries. For the professional looking for maximum ROI and fewer bit changes on the jobsite, the ANSI-compliant wear mark provides a clear indicator for when the bit no longer meets tolerance standards, ensuring every hole is spec-perfect.

• / Solid head carbide construction provides up to 5x longer life when encountering rebar.
• / Integrated rebar guards protect the bit from damage and prevent binding in hard aggregate.
• / Sharp centering tip allows for exact spot drilling, preventing bit walk on smooth surfaces.
• / Optimized flute design accelerates dust removal to keep the bit cool and improve battery efficiency.
• / ANSI wear mark indicator provides a visual reference to ensure holes meet anchor requirements.
